Abstract
An apparatus for controlling switching transients including a bus interface unit and a waveform shaper coupled to the bus interface unit and a peripheral device. The bus interface unit generates a number of control signals defining the beginning and end of an operation, where each control signal includes a transition from a first value to a second value over a period of time. The bus interface unit selects a critical control signal defined as the last control signal to start the operation and/or the first control signal to end the operation. The waveform shaper receives the selected control signal and modifies the control signal by increasing the period of time of the transition. The modified control signal is received by the peripheral device and a switching transient in the peripheral device is controlled.
